' Application filed Ju1y22, 1914. Serial No. 852,413.

State of North Carolina, have invented certain new and useful Improvements in Sash- Fasteners, of which the following is a speci- Y fication.

This invention relates to sash fasteners and has primarily for its object to automatically normally retain the window in a locked position, at the same time, permitting the window to be expeditiously operated when desired.

Another object of the invention is to positively preclude possibility of the locking shoe binding which would in any way interfere with the operation of the window, by the provision of rollers which facilitate the disengagement of the shoe from the window frame when it is desired to actuate the window in its casing.

Other objects as well'as the nature, characteristic features and scope of my invention will be more'readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of this specification.

Referring to the drawings: Figure 1 is a side elevational view of a fastener constructed in accordance with my invention, illustrating its application with a window and window frame, the top of the casing of the device being removed to disclose details, Fig. 2 is a perspective view of the locking. shoe, Fig. 3 is a detailed enlarged fragmentary elevational view showing the manner in which the coil spring is associated with the casing, Fig. i is a longitudinal sectional view taken on the line H of Fig. 1 and looking in the direction of the arrow, Fig. 5 is a perspective view of the casing showing the top removed therefrom, and Fig. 6 is a similar view of the top of the casing.

In the drawings wherein is illustrated the preferred embodiment of this invention, in order to illustrate the application thereof, a window frame 5 is provided which has slidably mounted therein in the usual manner a window 6.

My improved device comprises a casing 7 preferably made of metal and of a substantially oblong configuration, one of the sides thereof being removed while the opposite Specification of Letters Patent.

and being for a Patented NovQQ, 1915.

side is provided with a substantially semiovoid recess 8 which extends through the outer margin of the side in which it is formed as shown to advantage in Fig. 5. The casing is held in engagement with the window 6, approximately midway the ends, by screw-bolts 9, the latter serving the dual purpose of holding the casing on the window, as above set forth, and likewise retaining the closure 10 on the casing, the bolts 9 which extend through the casing 7 adjacent the frame .5 have rollers 11 mounted thereon, the latter being made of wood, metal or any other suitablevmaterial,

I purpose which will subsequently appear.

A shoe 12 is associated with the casing 7, which in the present instance is of an oblon configuration and has a strip 13 preferably made ofrubber secured to one face thereof, said strip adapted for engagement with the window frame 5 for holding the window in a predetermined position, at the same time, preventing mutilation of the window frame by the contact of the shoe therewith. EX- tending from the opposite face of the shoe 12 is a projection '14:, which assumes the configuration of an isosceles triangle and has pivotally mounted on the apex thereof one end of an operating lever 15, the opposite end thereof extending through the semiovoid recess 8 in the side of the casing 7, the terminal thereof having a handle 16 mounted thereon in order to facilitate the manipulation of the shoe 12'. As shown to advantage in Fig. 2, the projection 14 is arranged on the shoe 12 in close proximity to one of the longitudinal edges, the margins of the sides of the projections 14 adapted to engage the rollers 11 of the casing 7, at times, thereby causing the shoe 12 to positively bind against the window frame 5, at the same time facilitating its disengagement therefrom, when so desired, since when pressure is exerted on the handle 16, it is'scen that whichever of the rollers 11 the projection 14 is in engagement with will be rotated, by the friction which is created, thereby insuring a smooth operation.

In order to hold the shoe 12 normally in engagement with the window frame 5, an elastic element 15 which in the presentin: stance comprises a co-ilspring, a'convolution on one'end being engaged with the inner face the sides of the casing 7 adjacent the a pair of semi-ovoid recess 8 thereof, while a convolution on the opposite end is in engagement with an abutment 16, the latter being formed on the outer periphery of the operating member 15 adjacent its point of connection with the projection 14:, as shown to advantage in Fig. 1

In operation therefore, it is seen that the shoe 12 is normally forced into engagement with the window-frame 5 in view of the elastic element 15, and when it is desired to raise the window, pressure is exerted on the handle 16 of the operating lever, thereby compressing the spring 15 and causing the projection 14: of the shoe to be retracted into the casin 'Z, in which position it is seen that the shoe is disengaged from the frame 5, permitting the window to be raised or lowered in the frame As soon as pressure is released from the operating lever 15, the shoe 12 is, of course, automatically reengaged with the frame 5, thereby locking the window in the frame.

it will he understood that the above description and accompanying drawings comprehend only the general and preferred embodin en'ts of m invention and that various minor changes in details of construction, proportion and arrangement of parts may be made within the scope of the appended claims and without sacrificing any or the advantages of my invention.

Having thus fully described my invention, what I claim as new and desire to secure bv Letters Patent is:

1. in combination with a window-frame having a window slidably mounted therein, a casing mounted on said window, a plu- Copies of rality of rollers journaled in said casing, a shoe associated with said casing, having a projection extending therefrom which ies between said rollers, an operating lever arranged on said projection and extending through said casing, means mounted on said lever Ior normally holding said shoe in engagement with the window frame, said proj ection adapted to be retracted in said casing between the rollers when pressure is eXerted on said lever to permit of the raising or lowering of the window in the frame.

In combination with a window-frame having a window slidably mount-ed therein, a casing detachably associated with said window, rollers journaled in said casing, a shoe associated with the casing, having a triangular projection extending therefrom, between said rollers, an operating lever, one end of which is in pivotal engagement with the vertex of said triangular roiection and he opposite end entendin g beyond the casing to provide an operating portion, a coil-spring encircled on the shank of said operating lever for normally holding said shoe in engagement with the window-frame, said projection being frictionally engaged with said rollers, at times, whereby the projection is retracted in the casing when pressure is exerted on said operating lever, for disengaging the shoe from the window-frame.
